v0.1.2

Release 0.1.2

Fixes carried since 0.1.0:
- Bytecode caching disabled so verification gates measure the patched code
  instead of a stale .pyc left by the baseline run
- Windows backslash paths in --test-cmd/--lint-cmd no longer mangled
- Trailing newline no longer duplicated on every patch
- LLM transport/HTTP/response failures reported cleanly instead of as a
  raw traceback
- tree-sitter and typer dependency floors raised to versions that actually
  install and run (0.21/0.12 crash on fresh installs)
- pytest no longer tries to collect the bundled SWE-bench instances

v0.1.1 was tagged but a CI test bug blocked its publish; this supersedes
it with the test fixed.
